* harbour/source/rtl/errorapi.c
    + added protection against possible GPF when some assign methods
      were called without parameters

  * harbour/source/rdd/workarea.c
    * initialize uiFalgs also when DBS_FLAGS is not set

  * harbour/contrib/bmdbfcdx/bmdbfcdx1.c
    * fixed hb_cdxSkipFilter() declaration - it should be 'static' function

  * harbour/source/pp/ppcore.c
  * harbour/source/compiler/ppcomp.c
    + added support for changing all -k? switches by #pragma, f.e.;
         #pragma -ks+
         #pragma -kM-
         #pragma -kx1
         #pragma -kJ0

  * harbour/source/compiler/hbusage.c
    * changed -ks description

  * harbour/include/hbexpra.c
  * harbour/include/hbexprb.c
    * do not generate error message for negative indexes and
      [] operators are used for simple types when -ks option
      is used

  * harbour/include/hbvmpub.h
  * harbour/include/hbapi.h
  * harbour/source/vm/hvm.c
  * harbour/source/vm/extend.c
  * harbour/source/vm/itemapi.c
  * harbour/source/vm/memvars.c
    + added HB_IT_DEFAULT flags - it allows to check if item was changed

  * harbour/source/vm/memvars.c
  * harbour/include/hbvm.h
    ! fixed HB_IT_MEMOFLAG updating to be Clipper compatible. Here we are
      not Clipper compatible in one place: in clodeblock local parameters
      with memo values are marked as MEMO but if you leave function where
      codeblock were created then Clipper during detaching removes MEMO
      flag. In Harbour memo flag is kept.

  * harbour/include/hbvm.h
  * harbour/source/vm/classes.c
  * harbour/source/vm/hvm.c
    % improved speed of extended references used for SETGET methods
      and overloaded [] operators

  * harbour/include/hbapi.h
  * harbour/include/hbsetup.ch
  * harbour/source/compiler/hbcomp.c
  * harbour/source/vm/hvm.c
  * harbour/source/vm/macro.c
  * harbour/source/vm/cmdarg.c
    * removed HB_COMPAT_XHB flags - only one HB_COMPAT_XHB still exist
      in HVM in hashes.c - it will be removed soon.

  * harbour/source/common/hbverdsp.c
    * removed information about xHarbour compatibility mode - it's not
      longer used. We are emulating xHarbour behavior using external
      XHB library and standard compiler/HVM features

  * harbour/contrib/xhb/xhb.ch
  * harbour/contrib/xhb/xhbfunc.c
  * harbour/source/vm/arrayshb.c
    * moved XHB_AINS(), XHB_ADEL() from XHB lib to HVM as HB_AINS(), HB_ADEL()

    + added #pragma -ks+
    + added transaltion for hb_enumindex( <enumvar> )

  + harbour/contrib/xhb/xhbenum.c
    + added emulation for HB_EUMMINDEX()

    * do not add INET*() function wrappers for DOS builds or when
      HB_NO_DEFAULT_INET macro is set

  * harbour/contrib/xhb/xhbmsgs.c
    * added comment

  * harbour/contrib/Makefile

* harbour/include/hbapi.h
  * harbour/source/vm/itemapi.c
  * harbour/source/vm/garbage.c
    + added extended item references - it's universal reference which
      can be used by HVM for many different things without introducing
      new item types

  * harbour/include/hbexprb.c
    * respect -ks compiler also with <op>=, --, ++ operators

  * harbour/include/hbvm.h
  * harbour/source/vm/hvm.c
  * harbour/source/vm/classes.c
    + added extended references for SETGET methods used as object
      item references
    * use extended references to respect overloaded [] operator in
      object item references
    + added support for passing indexes to string item characters
      ( @cValue[n] ) by reference using extended references - extension
      enabled by -ks compiler switch and //flags:s RT switch. 
    + added hb_vmPushItemRef()

  * harbour/source/rdd/dbf1.c
  * harbour/source/rdd/usrrdd/usrrdd.c
    * use hb_vmPushItemRef()

  * harbour/contrib/xhb/xhbcomp.prg
  * harbour/contrib/xhb/xhbmsgs.c
    * overload +, -, *, %, ^, ++, -- in string and numeric scalar
      classes to emulated xHarbour behavior when 1 byte string is
      used as numeric value.
      Note: <nun> + <char1> in XHB lib gives numeric value when in
            xHarbour character. But because <nun> <anyOtherOper> <char1>
            in xHarbour gives numeric value then I guess that it's
            xHarbour bug and I should not replicate it, f.e.:
               proc main()
                  ? 1+"A", 131-"A", 33 * 2, 132 / chr(2), 133 % "C"
               return
    * overload +, - in hash scalar class to emulated xHarbour behavior
      for <hash> + <hash> and <hash> - <hash>
      Seems that now we can remove HB_COMPAT_XHB flag from HVM and keep
      Harbour compatibility only with -ks compile time switch and XHB
      library. Please make some tests with Harbour compiled without
      HB_COMPAT_XHB and xHarbour code using REQUEST XHB_LIB. It's possible
      that I missed sth but some basic test shows that our emulation is
      better then original and addresses places where xHarbour does not
      work at all or gives strange results, f.e.:

         #ifndef __XHARBOUR__
            request XHB_LIB
         #endif
         proc main()
            local h:={"ABC"=>123.45}
            ? h:abc
            h:abc+=1000   ; ? h:abc
            h["ABC"]+=1000; ? h:abc
            p(@h:abc)     ; ? h:abc
            p(@h["ABC"])  ; ? h:abc
         return
         proc p(x)
            x+=1000
         return

      or:

         #ifndef __XHARBOUR__
            request XHB_LIB
         #endif
         #include "hbclass.ch"
         proc main()
            local o:=myClass():new()
            o:setget:="ABC"; ? o:setget
            o:setget[2]:=42; ? o:setget
            o:setget[2]+=42; ? o:setget
            ? o:setget[2]+=42; ? o:setget
            ?
            o:var:="ABC"; ? o:var
            o:var[2]:=42; ? o:var
            o:var[2]+=42; ? o:var
            ? o:var[2]+=42; ? o:var
         return
         CREATE CLASS myClass
            VAR    var
            METHOD setget SETGET
         END CLASS

    * changed second parameter in RELTEXT() method to PHB_ITEM
      Now RELTEXT() works like FILTERTEXT() and the size of
      expression is not limited. It's a modification I wanted
      to make for a long time and I think that now is a good
      moment to make it together with HB_FT_* modifications
    - rmoved not longer necessary HARBOUR_MAX_RDD_RELTEXT_LENGTH

  * harbour/source/rtl/gttrm/gttrm.c

* harbour/include/hbclass.ch
    + added:
         ON ERROR FUNCTION <FuncName>
         OPERATOR <op> FUNCTION <FuncName> <scope>

  * harbour/include/hbapicls.h
  * harbour/source/vm/classes.c
  * harbour/source/vm/hvm.c
    + added support for overloading right side $ operator

  * harbour/contrib/xhb/xhbfunc.c
    * rewritten xhb_ains() and xhb_adel() in C

  * harbour/contrib/xhb/xhb.ch
    * changed AINS() conversion to be xHarbour compatible

  * harbour/contrib/xhb/Makefile
    + added xhb.ch to PRG_HEADERS so it's installed automatically
      during 'make install'

  * harbour/contrib/xhb/Makefile
  + harbour/contrib/xhb/xhbmsgs.c
  * harbour/contrib/xhb/xhbcomp.prg
    + added support for $ operator used with hashes and arrays
      on right side working _exactly_ like in xHarbour.
    + added support for negative indexes in used in [] operator
      for array and strings.
      Please remember that standard harbour build (without
      HB_COMPAT_XHB flag) generate warning for negative indexes,
      if you wan to pacify them then instead of var[-1] use var[(-1)]
    + added support for assign string characters with [] index.
      Please remember that for standard harbour build (without
      HB_COMPAT_XHB flag) you have to use -ks compile time switch
      if you want to assign strings in such way because this feature
      needs different PCODE, f.e. try to compile this code:
         proc main()
            local s:="ABC"
            s[(-1)] := "*"
            ? s
         return
      with and without -ks switch
    + added support for accessing hash items using OO interface, f.e.:
         proc main()
            local h:={"ABC"=>123.45,"XYZ"=>567.89}
            ? h["ABC"], h["XYZ"]
            ? h:ABC, h:XYZ
            h:ABC+=1000
            h:XYZ:=-2000
            ? h:ABC, h:XYZ
         return

      All of the above extensions are written in C code so the speed
      overhead is very small. Harbour evaluates PCODE faster then xHarbour
      so in speed tests where above operators are executed in loop without
      any other code the xHarbour results with native support are comparable
      with Harbour ones where above operators are overloaded using scalar
      classes so in normal code you should not find any difference with
      one exception for assigning characters in very long strings.

      Unlike Ads*() functions the Sx_*() ones can be used with any RDD
      and will work if RDD supports necessary functionality.

      The global settings in SIx3 are RDD dependent in Harbour, f.e.
      in SIx3 Sx_MemoExt() change MEMO file extensions in all SIX* RDDs
      but in Harbour only in default RDD driver.
      In Harbour default trigger function "Sx_DefTrigger" is not
      enabled by default. If user needs such functionality then he
      has to enable it himself using
         rddInfo( RDDI_TRIGGER, "SX_DEFTRIGGER", [<cRDD>] )
      f.e. this code:
         init procedure sx_inittrig()
            local aRDDs := { "DBF", "DBFNTX", "DBFCDX", "SIXCDX", ;
                             "RMDBFNTX", "RMDBFCDX" }
            local aRDDList := RddList(), cRdd

            for each cRdd in aRDDs
               if ascan( aRDDList, { |x| x == cRdd } ) != 0
                  rddInfo( RDDI_TRIGGER, "SX_DEFTRIGGER", cRDD )
               endif
            next
         return
      sets SX_DEFTRIGGER as default trigger in DBF* based RDDs.

      I still do not allow to encrypt tables with memo fields to not
      replicate SIx3 bugs which may cause data corruption.

* harbour/include/hbclass.ch
    + added new commands for scalar classes:
         ASSOCIATE CLASS <ClassName> WITH TYPE
                           ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|
                           NUMERIC|POINTER|SYMBOL
         ENABLE CLASS TYPE ALL
         ENABLE TYPE CLASS ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|
                           NUMERIC|POINTER|SYMBOL
      Please remeber that:
          ENABLE CLASS TYPE ALL
      and:
          ENABLE TYPE CLASS ...
      can be used in any place of code - this commands are translated to
          REQUEST HB<TYPENAME>
      so are not executed

  * harbour/source/vm/classes.c
    + added __clsAssocType( <hClass>, <cType> ) => <lOK>

  * harbour/common.mak
  * harbour/source/rtl/tscalar.prg
  * harbour/source/rtl/Makefile
  + harbour/source/rtl/tscalars.c
  + harbour/source/rtl/tscalard.c
  + harbour/source/rtl/tscalarh.c
  + harbour/source/rtl/tscalarl.c
  + harbour/source/rtl/tscalarp.c
  + harbour/source/rtl/tscalara.c
  + harbour/source/rtl/tscalaru.c
  + harbour/source/rtl/tscalarb.c
  + harbour/source/rtl/tscalarn.c
  + harbour/source/rtl/tscalarc.c
    + added scalar classes for basic types,
      Now it's possible to define messages also for basic item types.
      It's even possible to overload some not defined in HVM operators,
      f.e. in this example we overload operator "+" so it makes
        AADD( <aValue>, <xValue> )
      for code like <aValue> + <xValue>:
        #include "hbclass.ch"
        PROC MAIN()
            LOCAL a:={}
            ASSOCIATE CLASS MyArray WITH TYPE ARRAY
            a := a + "elem1"
            a += "elem2"
            a := a + "elem3"
            a += "elem4"
            ? a:asString, a:isScalar
            AEVAL(a,{|x,i|QOUT(i,x)})
        RETURN
        CREATE CLASS MyArray INHERIT __HBArray
           OPERATOR "+" ARG xValue INLINE AADD( Self, xValue ), Self
        ENDCLASS
      Operators which have default actions for given types defined in HVM
      cannot be overloaded.

* harbour/include/hbapicls.h
  * harbour/source/vm/hvm.c
    + added hb_clsDoInit() function to initialize classy .prg functions

  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyh
    % optimize automatically var[0] declaration and generate the same
      PCODE as for var:={}

  * harbour/source/rtl/tscalar.prg
    + added HASH, POINTER and SYMBOL scalar classes
    * changed NIL class to not use any instance variables

  * harbour/source/vm/classes.c
    + added support for scalar classes. Now at startup classy code looks
      for hb<TYPENAME> functions and try to execute them to register
      scalar classes. It's Class(y) compatible behavior and only the prefix
      of scalar ceases class function is different: 'CSY' in class(y) and
      'HB' in Harbour, f.e.: hbNumeric()
      If you prefer xHarbour like not automatic scalar class registration
      with some PP commands:
         ASSOCIATE CLASS <ClassName> WITH TYPE
                           ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|
                           NUMERIC|POINTER|SYMBOL
         ENABLE CLASS TYPE ALL
         ENABLE TYPE CLASS ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|
                           NUMERIC|POINTER|SYMBOL
         EXTEND [TYPE] ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|
                       NUMERIC|POINTER|SYMBOL WITH METHOD <SomeFunc>
      Then I can replace current code with it. If not then we should
      divide scalar cases definitions into separated files to allow
      easier overloading. I'm interesting in your opinions.

      Sorry but I had to make it because this fix was wrong and causes
      that code like:
            func f(v)
            if v

      was compiled without any warnings but wrong PCODE was generated.
      In some spare time I'll try to implement valid RETURN detection,
      now simply add RETURN NIL at the end of such functions - it will
      be removed by dead code eliminator.
    ! fixed memory leak when more then one .prg file was given as compiler
      parameter

      OnError(), f.e.: OnRestore() or sth like that and execute
      it after deserialization or object cloning.

  * harbour/utils/hbrun/Makefile

      Now hbrun can accept as first parameter .hrb or .prg file and if
      it's .prg file it's compiled and then executed just like .hrb one.
      In *nixes if you copy compiled hbrun to /usr/bin directory then
      you can add to your .prg files as first line:
         #!/usr/bin/hbrun
      and then after setting executable attribute you can directly
      execute them, f.e.:
         ./test.prg
      If you are using Linux then you can also chose default gt driver
      by dding to above line: //gt<name>
      F.e.
         #!/usr/bin/hbrun //gtstd

  + harbour/source/vm/hashes.c
  + harbour/source/vm/hashfunc.c
    + added hash items, f.e.:
         local h1 := {=>}, h2 := { "a"=>1.234, "b"=>2.345 }
         ? h2[ "a" ], h2[ "b ]
    + added support for DYNAMIC function declaration - it allow to define
      functions which are lately bound at runtime, f.e.:
         /*** t01.prg ***/
         dynamic func1
         proc main()
         local h:=__hrbload("t02.hrb")
         ? func1()
         return

         /*** t02.prg ***/
         func func1
         return "Hello!!!"

    % use new FUNCALL structure to hold EXTERNAL and DYNAMIC functions,
      it reduce memory usage, FUNCALL is much smaller then FUNCTION
    % use symbol scope bits when possible instead of making some linear scan
    + added new enumarator message: __ENUMKEY - it allow to access
      key value when hash item is base enumerator value, f.e.:
         proc main()
         local v, h:={"a"=>1.000,"b"=>2.000,"c"=>3.000}
         heval( h, { |k,v,i| qout( k, v, i ) } ); ?
         for each v in h
            ? v, "=>", v:__enumKey(), v:__enumValue(), v:__enumIndex(), ;
                       valtype(v:__enumBase())
            v += 0.123
         next
         ? ;heval( h, { |k,v,i| qout( k, v, i ) } )
         return
    + added C level hb_hash*() functions
    + added support for full HASH item cloning and updated array cloning
      to also clone nested hashes - please note that xHarbour does not do
      that, in xHarbour ACLONE() clones _ONLY_ nested arrays and HCLONE()
      _DOES_NOT_ clone _ANY_ nested items.

  * harbour/include/hbextern.ch
    + added hash functions HB_H*()
    * changed INET*() functions to HB_INET*()
    + added hash functions H*() and socket functions INET*() when
      HB_COMPAT_XHB is set

  * harbour/include/hbtypes.h
    + added missing HB_EXTERN_BEGIN / HB_EXTERN_END

  * harbour/include/hbpp.h
  * harbour/source/pp/ppcore.c
    ! added protection against automatic word concatenation in some cases
    ! fixed preprocessing expressions when match marker matches ';' token

  * harbour/source/rtl/Makefile
  + harbour/source/rtl/itemseri.c
    + added functions for item serialization: HB_SERIALIZE() and
      HB_DESERIALIZE() - these function are not binary compatible
      with xHarbour functions with the same names but make very
      similar job with the exception to serialization of codeblock
      and object variables - Harbour does not allow to serialize
      codeblocks and serialize objects as arrays.
      In most cases these functions can replace the xHarbour ones
    + added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered
      by HB_COMPAT_XHB macro - this functions are only for compatibility
      with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is
      dummy function which returns first parameter and HB_DESERIALNEXT()
      is a simple wrapper to HB_DESERIALIZE() so it's not necessary to
      use them.

  * harbour/source/rtl/hbinet.c
    * changed INET*() functions to HB_INET*() and enable them for default
      build
    + added INET*() functions wrappers covered by HB_COMPAT_XHB macro

  * harbour/source/rtl/hbrandom.c
    + added HB_RANDOMINT() - xHarbour compatible

  * harbour/source/rtl/len.c
    + added support for HASHes

  * harbour/source/rtl/valtype.c
    + added support for HASHes
    + added set of HB_IS*() functions - they are a little bit faster then
      calling VALTYPE( v ) == <cVal>
    - removed HB_ISBYREF() - this function cannot longer work, it was using
      a Clipper incompatible anomalies in passing variables by reference I
      fixed so it has to stop to work. If it will be realy necessary to
      implement HB_ISBYREF() function then please inform me - it will have
      to be done at compiler level or with some much deeper HVM stack
      checking.

  * harbour/source/vm/extend.c
    ! fixed hb_extIsArray() and hb_extIsObject() to work well with
      parameters passed by reference.
      Please note that now hb_extIsArray() return TRUE only for pure arrays
      not object values.

  + harbour/contrib/tip/utils.c
    + added TIP library - code borrowed from xHarbour



   Please test - a lot of above code is not well tested, also some peaces
   were written over year ago for different things (f.e. serialization for
   NETRDD) and now I collected them and committed.
   The TIP library was not tested at all. It can be compiled but I cannot
   say if it works - I hope that people familiar with it can make necessary
   test and fixes.
   It's also not the final version of low level HASH item code. I'm working
   on more efficient structure which uses binary tries but I cannot say when
   I'll finish it (maybe in this weekend or maybe in next year) so I committed
   working version now even if I'm not happy with overall performance (BTW
   not worser then in xHarbour)

  * harbour/source/vm/itemapi.c
    ! added protection against cyclic references in arrays
    * eliminated action parameter from hb_vmRequestReenter() /
      hb_vmRequestRestore()
    * moved s_lRecoverBase and s_uiActionRequest to HB_STACK structure
      for future MT HVM version
    + added internal item structure hb_struRecover - it's not real item
      but this structure is used to keep information about BEGIN SEQUENCE
      data - it reduce HB_STACK usage
    + added support for ALWAYS clause in BEGIN SEQUENCE
      The syntax is:
         BEGIN SEQUENCE
            <code>
         [ RECOVER [ USING oErr ] ]
            <recoverCode>
         [ ALWAYS ]
            <alwaysCode>
         END [ SEQUENCE ]
      It's guaranteed that <alwaysCode> is _ALWAYS_ executed even if
      inside <code> or <recoverCode> some new exceptions like RETURN,
      BREAK or QUIT will appear.
      Please note that when the following code is executed:
         BEGIN SEQUENCE
            <code>
         ALWAYS
            <alwaysCode>
         END
      (without RECOVER clause) then BREAK exception inside <code> is not
      recovered, <alwaysCode> is executed and then BREAK exception is
      passed to outer BEGIN SEQUENCE. This is the same semantic as
      used in TRY / [ CATCH ] / FINALLY / END
      Those of you who prefer to use TRY / CATCH / FINALLY / END instead
      of BEGIN SEQUENCE / RECOVER / ALWAYS / END can simply add to your
      source code:
         #command TRY               => BEGIN SEQUENCE
         #command CATCH [ oErr ]    => RECOVER [ USING <oErr> ]
      and:
         errorBlock( {|oErr| break( oErr ) } )
      Though instead of 'break( oErr )' I suggest to use some small function
      which will support some basic recovery/substitute operations like in
      default errorsys() and LockErrHandler() to not break existing code
      which may depends on the default behavior.
      If you want I can add direct support for TRY / CATCH / FINALLY / END
      but I'm not sure it's really necessary.
      Please note also that in Harbour ALWAYS code is execute even for QUIT
      excpetion.
      When <alwaysCode> is executed current exception is stored and restored
      when is finished. If new exception appears inside <alwaysCode> then
      restored exception depends on the priority in the following order:
         QUIT     // highest priority
         BREAK
         RETURN
      If both exceptions have the same priority and contain additional value
      (error object in BREAK or return value in RETURN) then the recently set
      one is restored. It's similar behavior to destructor code.

  * harbour/source/common/hbstr.c
    * moved one character length string table (hb_szAscii) from hvm.c
      to use it also in compiler and preprocessor

  * harbour/source/compiler/ppcomp.c
  * harbour/source/pp/ppcore.c
  * harbour/source/pp/pplib.c
    * tuned error messages to be more Clipper compatible
    % use static strings from hb_szAscii

  * harbour/source/rtl/alert.prg
    * use hb_gtInfo( GTI_FULLSCREEN ) to detect type of GT driver
    ! some minor fixes
      TOFIX: we have to also use GTI_ISCTWIN or add window allocation
             to standard GT drivers to be Clipper compatible when CTWIN
	     is used - In Clipper Tools ALERT() works in differ way then
	     the standard one. It creates separate window box to display
	     data, supports SETKEY(), etc. I'll think about adding some
	     extended support for ALERT() and similar operations (f.e.
	     separate debugger windows) to GT API so it will be also
	     possible to overload standard alert() command by GUI message
	     box in GTGUI and similar GT drivers.

  * harbour/include/hbapiitm.h
  * harbour/source/vm/itemapi.c

  * harbour/include/hbexprb.c
    ! use HB_P_DUPLUNREF instead of HB_P_DUPLICATE when assign is used in

         x:=10
         f(y:=iif(.t.,@x,))
         ? x, y
         func f(x)

  * harbour/include/hbver.h
  * harbour/source/common/hbver.c
    * changed status to "devel"

  * harbour/source/common/expropt2.c
    * disabled setting NIL when iif(.t.,,sth()) is optimized to avoid
      warning when iif() is used as statement - to fix number of parameters
      passed to function in code like f(iif(.t.,,sth())) we will need a
      little bit deeper modification

  * harbour/source/compiler/complex.c
    * added hack for potential problems caused by WITH OBJECT syntax, f.e.
      in code like:
         proc p(obj,x)
         case:=myCaseClass():new()
         retu:=myCaseClass():new()
         WITH OBJECT obj
            do case
               case x==nil
               case:value()
               case:action()
                  retu:sth()
            end
         END
         case:action()
         retu:sth()
         return
      case:action(), case:value(), retu:sth() can means two different things
      and compiler cannot guess which one should use. It cannot be fixed
      because it's caused by bad WITH OBJECT syntax. In xHarbour constractions
      like case:value() or retu:sth() are always used as in  WITH OBJECT
      context what is not Clipper compatible. I do not want to introduce
      such limitations. We have two choices: change WITH OBJECT syntax or
      add some hack to "hide" the problem a little bit. Now I intorduce
      ugly hack which check number of spaces between ':' so
         case :action()
      is compiled as case condition using WITH OBJECT message and
      case:action() as sending message to object in case variable

  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
    + added support for passing base value to FOR EACH by reference.

  * harbour/source/vm/arrays.c
    * use hb_itemMoveRef() in AINS()/ADEL() to avoid creation of cyclic
      reference chains

  * harbour/source/vm/debug.c
  * harbour/source/vm/memvars.c
    * use hb_itemCopyToRef() to avoid creation of cyclic reference chains

  * harbour/source/vm/classes.c
  * harbour/source/vm/hvm.c
    * use hb_itemMoveToRef() to avoid creation of cyclic reference chains
    + added support for for writable string enumerators, f.e.:
         proc main()
         local s, c
         s:="abcdefghijklmnopqrst"
         for each c in @s
            if c$"aeio"
               c:="*"
            endif
         next

      It fixed some possible buffer overflow but it's also possible that
      it will exploit some some hidden so far problems but I strongly
      prefer to know about them ASAP to fix them before final 1.0 release.
    ! fixed bug I introduce in codeblock falgs which disabled early macro
      evaluation in codeblocks.
    ! added missing protection against execution by bison destructor for
      used CBSTART token on syntax error.
    % use PP stringify logik added for FLEX support to remove all redundant
      spaces in stringified for early macro evaluation codeblocks and add
      spaces between operators if after preprocessing they were removed.
      Now we are supporting also some code which cannot be compiled by
      Clipper.
    % cleaned and improved the speed of printer redirecting in console code.
      Chen please check if CG still reports problems and if not ubdate
      TODO/TOFIX or inform me about them.
    * some cleanups in building process for different *nixes: MacOSX, SunOS,
      *BSD, etc.
    * removed not longer necessary (I hope) compiler flag to force default
      'char' type as signed. Now Harbour should work with signed and unsigned
      char without any problems. To other developers: please remember that
      when you are using 'char' as 8 bytes signed integer then it's a bug.
      Always explicitly use: 'signed char' in such case. On some platforms
      it's not possible to set default type for 'char' so if you hardcode
      that 'char' is signed or unsigned somewhere then code will not be
      portable. Chen if you will find a while to also rebuild Harbour with
      BCC and -K switch to make some tests with CG then I'll be thankful.

  * harbour/source/vm/arrays.c
  * harbour/source/vm/estack.c
  * harbour/source/vm/hvm.c
  * harbour/source/vm/proc.c
    + added startup symbol to hb_stack. It gives very good stop
      condition for all procedures which trace stack calls and
      resolves the problem with hb_stack.pBase which was never
      pointing to valid function/procedure symbol when no symbol
      was put on HVM stack. Now after hb_stackInit() the first
      item is allocated for "hb_stackInit()" symbol so hb_stack.pBase
      is always a pointer to valid function/procedure symbol.
    * changed the guard condition for buggy code in hb_stackPop()
      and similar code from:
         hb_stack.pPos < hb_stack.pItems
      to:
         hb_stack.pPos <= hb_stack.pBase
      The old condition was generating usable error message only in the
      startup function. In deeply called functions it was only waste of
      CPU time on one of the most often call functions. Before it was
      activated internal stack structures were corrupted.
      If we were leaving for many years without really working stack
      underflow protection then maybe we should think about disabling
      it at when HB_STACK_MACROS are used and keep it only in real
      stack functions for HVM developers. Single protection in
      hb_stackOldFrame() I've just added is enough for basic C code
      validation.
      I created the second version of stack macros without it in
      hbstack.h but I would like to hear other developers opinion.

* harbour/include/hbclass.ch
    * most of the rules rewritten
    ! fixed some wrong rules and general cleanup
    + added additional code validation
    ! fixed compilation of more then one class in single file.
      Now it's even possible to declare all classes at beginning of
      single file and then implementing their methods in any order
    ! fixed using static classes and classes
    ! fixed compilation without <ClassName>_ prefix in method names
    + added support for HB_CLS_NO_DECORATION macro which disable
      adding <ClassName>_ prefix to method names - this macro is
      set by default when HB_SHORTNAMES is set.
    + added support for declared parameters validation - it can be
      disabled with HB_CLS_NO_PARAMS_ERR and I had to disable it
      by default due to problems with our preprocessor.
      Ryszard seems that our PP has serious problems with decoding
      directives when there is no space between symbol and some other
      non symbol character. I had to add some workarounds and even
      introduce buggy rules to make it working. Please look at it.
      You can remove #define HB_CLS_NO_PARAMS_ERR from hbclass.ch
      and try to rebuild Harbour core code to see the problem.

  * harbour/include/hboo.ch
  * harbour/source/vm/classes.c
    + added support for new primitive message: HB_OO_MSG_PERFORM

  * harbour/source/rtl/tclass.prg
    - removed <lPersistent> parameter from HBClass messages and
      internals data. Persistent is supported as scope bit and
      separate variable was redundant.
    - removed stripping of () from message names. Here is not a place
      to fix wrong preprocessor rules.

  * harbour/utils/hbtest/rt_class.prg
    * use: METHOD PROCEDURE ... CALSS ...
      instead of: PROCEDURE ... CALSS ...
      The first version is preferable syntax.

  * harbour/source/debug/dbgtmenu.prg
  * harbour/source/rtl/checkbox.prg
    ! fixed some parameters in method declaration - global cleanup
      will have to wait for preprocessor fixes

   Hi all,
   Please make test with current hbclass.ch code.
   I hope that I haven't broken too much things ;-) but I rewrite
   from scratch most rules and it's possible that I missed sth or
   made some stupid typos. Current version is much shorter and should
   be easier to updated. For sure I've intentionally changed one thing.
   CLASSDATA was ignoring SHARED attribute and always created shared
   class variables. Seems that it was long existing typo but the fix
   may interact with already existing code which needs SHARED class
   variables but does not use SHARED clause in CLASSDATA declaration.
   In such case please update it and add missing SHARED.
   Also in the end of CLASS declaration we have:
      [ ; #translate Super( <SuperClassN> ): => ::<SuperClassN>: ] ;
      [ ; #translate Super( <SuperClass1> ): => ::<SuperClass1>: ] ;
      [ ; #translate Super(): => ::<SuperClass1>: ] ;
      [ ; #translate Super: => ::<SuperClass1>: ] ;
      [ ; #translate ::Super : => ::<SuperClass1>: ]
   These rules introduce very serious bug - they are breaking supercasting
   in code which makes sth like:
      ::super:super:super:msg
   or in any other code which sends SUPER message to some other class
   objects. I will have to remove them. At least the last three ones.
   There were some other things I wanted to write about but it's too late
   and I'm to tired - sorry. If you will have any question please ask. if
   you will notice some problems with current rules please inform me.

* harbour/source/vm/classes.c
    * allow to access object variables using assign messages without
      parameter. I do not want to add symmetric behavior for access messages
      though it's technically possible but such things should be controlled
      by programmer because access messages can have less restricted scoping
      then assign ones (READONLY) so I'll add new rule for it in hbclass.ch

  * harbour/source/vm/hvm.c

      be removed in the future.

  * harbour/include/hbapicls.h
    + added definitions for hb_clsCreate(), hb_clsAdd(), hb_clsAssociate()

  * harbour/include/hbapierr.h
  * harbour/source/rtl/errorapi.c
    + added hb_errFuncName - pseudo function name which can be used as
      operation description in new error object. It should help to simplify
      some code and fix function names when RT error is generated from C
      function which can be executed from different .prg functions.

  * harbour/include/hbclass.ch
    + added some missing Classy(y) compatible object variable type
      descriptions: Int, Integer, Block

  * harbour/source/rdd/dbfcdx/dbfcdx1.c
    ! disabled early retrieving from the cache key position and key count

  * harbour/include/hbvm.h
  * harbour/source/vm/hvm.c
    + added: void hb_vmPushEvalSym( void ) for the code which do not
      want to access any [P]HB_SYMB structures
    * changed symbol name in hb_symEval from __EVAL to EVAL and modified
      hb_symEval registration method to not register hb_vmDoBlock as global
      function. Having PHB_DYNS address for "EVAL" in hb_symEval.pDynSym
      allows to eliminate some strcmp() when we are looking for EVAL public
      symbol.
    ! fixed symbol table updating in PCODE functions for future multi module
      .hrb files

  * harbour/source/vm/proc.c
    * use hb_symEval.pDynSym instead of strcmp()

    % use hb_symEval.pDynSym
    + added support for object variable type scope checking like in Class(y).
    ! fixed typo in pushing object class variables by reference
    % s_pClasses is now indexed directly by class handle
    % some other optimiztions
    ! make hidden and non virtual invisible in child classes if it overloaded
      some other non hidden method. In such case the overloaded method is used
      and can be accessed.

* harbour/source/vm/itemapi.c
    * minor modification in function order to group together the ones
      which can operate on reference counters
    + added additional stop condition in hb_itemUnRef() - we will have
      to make some modifications for the code which execute hb_itemUnRef()
      to resolve some possible conflicts with operators overloading and
      compiler optimizations

  * harbour/source/vm/classes.c
    * do not inherit friends - seems that our classes code was too
      friendly ;-)
      It also effectively resolves logical problem with accessing
      overloaded non virtual methods from friends.
    + added __clsLock( <hClass> ) - it locks any farther class
      modifications and can be used if programmer wants to be sure
      that no one will try to hack his class definition. It's very
      important when programmers work in a team on bigger project.
      Please do not add to CVS any __clsUnLock() functions - if someone
      needs it then he can create his own custom HVM build.
    * code cleanup

  * harbour/source/vm/eval.c
    + added hb_execFromArray() - idea and syntax borrowed from xHarbour's
      HB_ExecFromArray() by Giancarlo Niccolai though it's independent
      implementation. Now when we have support for functions with variable
      number of parameters then we need sth like this function to fully
      benefit from new feature. The following syntax is supported:
         hb_execFromArray( <cFuncName> [, <aParams> ] )
         hb_execFromArray( @<funcName>() [, <aParams> ] )
         hb_execFromArray( <bCodeBlock> [, <aParams> ] )
         hb_execFromArray( <oObject> , <cMethodName> [, <aParams> ] )
         hb_execFromArray( <oObject> , @<msgName>() [, <aParams> ] )
      or:
         hb_execFromArray( <aExecArray> )
      where <aExecArray> is in one of the following format:
         { <cFuncName> [, <params,...>] }
         { @<funcName>() [, <params,...>] }
         { <bCodeBlock> [, <params,...>] }
         { <oObject> , <cMethodName> [, <params,...>] }
         { <oObject> , @<msgName>() [, <params,...>] }

  * harbour/source/rtl/symbol.prg
    * removed C code inside #pragma BEGINDUMP/ENDDUMP
      now it's only .prg code which uses variable parameters function
      and hb_execFromArray()

    ! fixed bug in real codeblock scoping which was exploited by

    * changed ACCESS messages to ASSIGN ones when object item
      reference is created for proper READONLY scope checking.
      The reference to object variable can be created only when
      caller has sufficient ASSIGN privileges.
    + added FRIEND CLASS and FRIEND FUNCTION support.
      It's enough to add class definition:
         FRIEND CLASS <classFunc1> [, <classFuncN> ]
      and/or:
         FRIEND FUNCTION <FuncName1> [, <FuncNameN> ]
      and all methods of given class or given function will be able
      to access private variables.
      Warning!!! Friends cannot access overloaded non virtual methods.
                 This feature is available _ONLY_ for real class members.
    + added MODULE FRIENDLY to class definition. It causes that all other
      functions and classes defined in the same .prg module will have
      friend privileges. In such way works xHarbour and there is now way
      to disable this "feature" what is IMHO bug. In Harbour programmer
      has to explicitly enable it (until he will not change / add new
      preprocessor rule and set it as default ;-)). Syntax:

      [P]HB_SYMB in 3-rd party code

  * harbour/source/vm/estack.c
    * added protection against possible GPF after executing
      hb_stackBaseProcOffset() when first item on the stack
      was not HB_IT_SYMBOL - it can happen in some seldom

                          or directly by: func( @a[ <exp> ] )

     for easier modifications in the future.

  * harbour/source/vm/classes.c
    * removed hb_objGetpMethod() - I hope it's not longer used
    * added real codeblock scoping.
      In Clipper there is no information where the codeblock where
      created and what priviladges/scopes it should has.
      Class(y) to resovle this problem when codeblock is executed scans
      the HVM stack for the nearest method call and takes scopes defined
      for this method. It's a workaround which allow to break standard
      access rights though seems reasonable when it's not possible to
      store information where the block is created. I've added to block
      item structure information about class and method where code block
      was created so we can use the exact method priviladges.
      Now Harbour classy code can work exactly like Class(y) when compiled
      with -DHB_CLASSY_BLOCK_SCOPE and with real code block scoping when
      compiled with -DHB_REAL_BLOCK_SCOPE. I set the second (real code
      block scopes) as default. If you think we should be strict Class(y)
      compatible here then please inform me and I'll change default setting.

* harbour/include/hbapicls.ch
    * added HB_EXPORT to public functions and some internal covered by
      _HB_API_INTERNAL_ macro

  * harbour/include/hboo.ch
    + added HB_OO_CLSTP_NONVIRTUAL and HB_OO_CLSTP_OVERLOADED

  * harbour/source/rtl/tclass.prg
    ! do not add supercast class messages - now it's done automatically
      by __clsNew() function with proper instance area offset updating
    ! enumerate instance class datas in __clsAddMsg() from 1 - inherited
      instance variables are managed internally by classy code with
      proper instance area offset updating
    ! use __CLS_CNTCLSDATA() as start offset for class data. Do not
      try to calculate it yourself - some of super classes can be ignored
      when they are appear in the inheritance tree more then once so it's
      not possible to calculate class data or instance data start offset
      using simple sum of class or instance variables in super classes.

  * harbour/source/vm/classes.c
    ! fixed instance area casting
    ! fixed class variables casting
    ! fixed multi-inheritance when the same class can apear more then
      once in super classes tree.
    ! Do not add unnecessary instance variables for the same class when
      it's inherited more then once.
    ! Do not add unnecessary class variables for the same class when
      it's inherited more then once.
    ! Do not add unnecessary initialization class and instance variables
    + added support for non virtual messages
    + added support for static and casted scoping
    + super cast messages added automatically. They are used to dynamic
      recalculation of instance are offsets and to avoid multiple inheritance
      of the same class so please do not overload them or you will have as
      result something what we have before recent modifications in the
      instance and class data area. Just simply run tests/clsccast.prg
      and tests/clsicast.prg compiled with current CVS code and last
      release code or with xHarbour and compare the results.
      Also Class(y) does not pass these tests and I do not know if any
      other dynamic OOP model in xbase languages can properly address it.
      BTW maybe I should add RT error when .prg code will try to delete
      or overwrite class cast message. For me it seems to be reasonable
      and what's your opinion?
    * make hidden class members non virtual by default. It can be disabled
      by compiling classes.c with -DHB_VIRTUAL_HIDDEN but IMHO keeping
      HIDDEN members as virtual causes that they are not really HIDDEN
      because subclasses can simply overwrite them. It also means that
      it's not possible to create class with some private data and
      methods which will never interact with any subclass code created
      by other programmers where name conflict can appear. So one of
      the most important OOP features is missing in such case.
      See tests/clsnv.prg as an example for non virtual hidden members.

  + tests/clsicast.prg
    + added test code for proper instance area allocating and casting

  + tests/clsccast.prg
    + added test code for proper class data allocating and casting

  + tests/clsnv.prg
    + added test code for non virtual hidden class members

   Now we should be able to create and class model even replicate the
   static one like in C++ using current class engine which still fully
   supports dynamic bindings. It consumes less memory and due to much
   more efficient hashing it should be faster then it was though some
   other minor optimization can be add and I'll plan to make them in
   some spare time.
   The item type verification in assignment is still missing. I'll add
   it when I'll collect some statistic informantion I'd like to ask
   [x]Harbour users. I need these information to tune some internal
   structures where I can balance between speed and memory allocation
   to statistically optimal form.

   Marek asked me to add passing object datas by reference and I'll do
   that but I'd like to ask Ryszard to add support for:
      @<oVar>:<message>
   to compiler. I'll implement all other HVM modifications. If you can
   please also add support for:
      <oVar>:&<cMsgName>[(...)]
   For this we do not need any HVM modifications or new PCODEs.
   We are supporting xBase++ macro list compilation in:
      cList:="1,2,3"
      x := aVar[ &cList ]
      aVar:={ &cList }
      func( &cList )
   But we do not support:
      <oVar>:<message>( &cList )
   IMHO it looks ugly. If we have this syntax for function call then we
   should also support it in message sending.
   Ryszard can you make necessary compiler modifications?
   I'm also thinking about adding support for variable parameters
      func myfunc(...)
      [...]
      return xVar
   In few cases it will help to encode some function much more efficient
   then now.

   I'll add Class(y) compatible functions used in class(y) header files
   so it will be possible to use original class(y) .ch files in Harbour
   though it will not be the most efficient because we have @func() operator
   which gives better performance then using codeblocks. Anyhow classy
   create separate meta class for each class with CLASS members and
   <clasName>() function always return such meta class object so for full
   Class(y) compatibility we need to generate differ .prg code.
   But all such modifications now can be done on preprocessor and
   .prg level and they will not need .c code modification.
   We should make them to give user interface for our new OOP features.

   Now I'm waiting for reports about any problems with current classy
   code.

* harbour/include/hbapi.h
  * harbour/source/vm/hvm.c
  * harbour/source/vm/codebloc.c
  * harbour/source/vm/arrays.c
    * moved static base offset from hb_struBlock structure
      to HB_CODEBLOCK structure
    + added hclass member to hb_struBlock - it will be used in
      the future for checking codeblock scope in classy so we will
      real scope checking also for messages sent from codeblocks.
    - removed supercast and superoffset members from hb_struArray
      structure.

  * harbour/include/hbclass.ch
    * added class(y) like
         @:<MessageName>([<MsgParams,...>])
      send operator. It's not exactly the same as in class(y) where
      this operator is hardcoded to executing function directly,
      needs method name instead of message name and is linked statically.
      In Harbour this operator uses message name so can be used also for
      instance variables and make dynamic casting to the class from which
      current method is inherited. In short words sending messages to @:
      instead of :: causes that they work like non-virtual messages in
      C++ mode.
      If you do not use the same method body in different classes
      then you can also use explicitly self casting:
         ::<myclass>:<msgname>[(...)]
      and it will be a little bit faster

  * harbour/include/hboo.ch
    + added: HB_OO_MSG_ASSIGN, HB_OO_MSG_ACCESS,
             HB_OO_MSG_CLSASSIGN, HB_OO_MSG_CLSACCESS
      They should be used insted of HB_OO_MSG_DATA and HB_OO_MSG_CLSDATA
      This resolves problems with name conflicts when we were detecting
      type of message (ACCESS/ASSIGN) by checking the first character
      in message name. F.e. now it's possible to create exported instance
      variable called __WithObject and it will be used in all WITH OBJECT
      statement instead of the base object value. It's simple and effective
      WITH OBJECT overloading.
      I kept backward compatibility for HB_OO_MSG_DATA and HB_OO_MSG_CLSDATA
      but I strongly suggest to update code to use new constants.
    + added HB_OO_MSG_REALCLASS

  * harbour/source/rtl/objfunc.prg
  * harbour/source/rtl/tobject.prg
  * harbour/source/rtl/tclass.prg
    * use HB_OO_MSG_[CLS]{ASSIGN,ACCESS} instead of HB_OO_MSG_[CLS]DATA

  * harbour/source/rtl/tclass.prg
    + added REALCLASS message to creted classes - it's used for @: operator

  * harbour/source/vm/classes.c
    * updated for above modifications
    * calculate instance area offset in supercasting dynamically - it
      will allow to eliminate multiple instance area allocating when
      in the inheritance tree the same class exists more then once and
      also quite easy add support for non-virtual messages.
    ! fixed GPF in __CLSINSTSUPER() class function generate HVM exception
    % do not inherit unaccessible inline blocks
    * some other minor optimization, fixes and code cleanups

  * harbour/source/rdd/usrrdd/usrrdd.c
    ! fixed HB_TRACE message

  * harbour/source/rtl/errorapi.c
    ! generate internal error if ErrorNew() function does not return an object

  * harbour/source/macro/macro.y
    * replaced TABs with SPACEs

* harbour/include/hbexprc.c
    ! fixed bug in wrong integer negating, f.e.:
         proc main(); local i:=0; i-=-32768; ? i; return
    ! fixed PCODE generated for +=, -=, /=, *= expressions when right side
      of expression is undefined variable - it's possible that it will be
      field and we will have RT error. It fixes tt4.prg example form TODO
      file.

  * harbour/TODO
    - removed tt4.prg example from TOFIX

  * harbour/source/vm/classes.c
    ! fixed supercast message validation

  * harbour/source/vm/hvm.c
